What Guy Mannerisms Drive You Nuts?

I twirl my hair when I'm tired. Luckily, my roommate Erica twirls her hair too, so at night in the apartment, we just watch Bravo TV, talk smack, and twirl our hair. It's all good. But I can be self-conscious about it around other people because, as my mom says, it's annoying. When she and I watch TV, she'll see me twirling out of the corner of her eye and say, "You're TWIRLING," and I do my best to stop.

This is totally random, but right now I'm freelancing in a building with a culinary institute on the first floor. Yesterday, the students must've burned a roast, because the fire alarm went off and we had to evacuate. I was looking for a hottie chef, but didn't find one.

I gotta watch these mannerisms, or whatever they are.

Beth was telling me she once dated a guy who would put his hands on his hips, but in that weird way, where the fingers are pointing down. I had to laugh! It's such a tiny thing, but I imagine it would be so unattractive. Where do people get these mannerisms?

Someone the other day was complaining about men who only breathe through their mouth! A mouth-breather! Too funny!

What about knee-bouncing, knuckle-cracking, nail-biting, hand-gesturing, earlobe-tugging, nose-picking, or constant bangs-touching? What guy mannerisms drive you to the edge?
